[jdk13u-dev] RFR: 8247753: UIManager.getSytemLookAndFeelClassName() returns wrong value on Fedora 32

[Yuri Nesterenko]

This patch does change some code inside a condition clause in a test. Now, in jdk17 that condition (so, context for this fix) checks for linux only but in jdk13 it checks also for solaris. Other than that, patch goes clean.
